Transport: stdio
Category: Docs, sheets & office work

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "csvto": {
      "command": "npx",
      "args": [
        "-y",
        "csvto-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add csvto -- npx -y csvto-mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "csvto": {
      "command": "npx",
      "args": [
        "-y",
        "csvto-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "csvto": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "csvto-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Csvto MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.2) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

csvto

CSV, JSON and Excel conversion that runs where your data already is.

[`csvto-mcp`](packages/mcp) — an MCP server. Point your AI assistant at a file path; it converts locally and writes the result beside it. Nothing is uploaded, and file contents never pass through the model's context.
[`@csvto/core`](packages/core) — the conversion engine. No DOM, no fs, no network, so the same tested code runs in a browser, in a local MCP process, or on a server.

The same engine powers the browser tools at [csvtosite.com](https://csvtosite.com), where conversion happens client-side and files are likewise never uploaded.

Install the MCP server

claude mcp add csvto -- npx -y csvto-mcp

Or in any MCP client's config:

"mcpServers": { "csvto": { "command": "npx", "args": ["-y", "csvto-mcp"] } } }

Requires Node 18+. Full tool list and behaviour: packages/mcp/README.md.

Types are inferred per column, not per cell

This is the part that matters, and where most converters quietly corrupt data. A column converts to numbers only if every value in it survives the round trip exactly. If one value would change, the whole column stays text:

01234 keeps its leading zero instead of becoming 1234
A 16-digit account number stays itself instead of becoming 1.23457E+14
1250.50 keeps its trailing zero instead of becoming 1250.5
A column never ends up as a mix of numbers and strings

Verified in tests: 01234 survives a CSV → xlsx → CSV round trip intact.

Develop

npm install

npm test # 49 tests npm run build

packages/core must stay environment-free — no window, no fs, no fetch. That constraint is what lets one tested engine serve every surface.
